Chrono Front

Command a small expeditionary force on a crystal-rich island: establish a production base, hold off the attack waves, then destroy the hostile Command Nexus. Camera work is most of the early game. WASD or the arrow keys pan, the wheel zooms, middle-mouse or right-drag rotates, and left-dragging empty terrain grabs the map. Left click selects; right click orders — move on terrain, attack an enemy, or send a collector to crystals. Shift adds to a selection, double-click takes the nearby units of the same type, Ctrl+1–9 assigns control groups, and Q then click attack-moves. X stops, H jumps to headquarters, and Space jumps to the latest combat alert. Tablets work too: tap an owned unit or building to select it, then tap terrain to move, an enemy to attack, or crystals to harvest. One finger drags the camera, and the minimap and − / + buttons handle navigation. Pause stops the simulation without freezing the camera, so you can still look around while you think.
